I said I would keep you informed as things developed and so I am, by asking another related question.
Update: Most of my time lately has been given over to my job (dam it) and trying to get some funding for the project, which is going OK.
I have also developed conceptual aspects of the project and I now have a more specific idea of what I need it to do, technically I believe it actually makes it simpler.
I intend to have a manually operated crank, this would be ratchet so one way only. The individual would turn the crank which would stimulate the image change.
What I believe would be the best way to do this would be using the IR pulse counter, much like a mouse. Each change of state (or maybe each return to state) in the IR switch would send the pulse via serial for a pc to receive.
So much like my normal questions are their any basic tutorials that demonstrate this activity, what IC would be best for carrying this out?
Thanks for any help, advice.
